Extracting Latest Date

I have a db which stores all my sales transactions.
The task is to extract the buy price(price) for each item(ItemCode) where the
date is the latest for each item.

For Example:
Sales Table
ItemCode Qty Price Date
-------------- ----- -------- --------
XYZ 2 23.50 12/03/05
XYZ 3 23.50 13/03/05
XYZ 2 99.99 14/03/05
ABC 14 88.88 01/01/05
RDB 12 77.30 21/04/05
RDB 23 23.35 02/05/05

I would then require only

ItemCode Qty Price Date
-------------- ----- -------- --------
XYZ 2 99.99 14/03/05
ABC 14 88.88 01/01/05
RDB 23 23.35 02/05/05

How do i write a query to extract the data?
Need help with a project of mine....really stuck with this one..Thank you
